SAND-REEL FOR oRituNe-MAoi-ums.

SPECIFICATION forming part of Letters Patent No. 413,733, dated Qotober 29, 1889. I Application filed December 7, 1888. Serial No. 292,905. (No model.)

its object to provides. reel of simple and do.-

rable construction, in which the friction-pulley willsbe free from cleats, and wherein the shaft will be stronger than heretofore and not liable to as rapid decay; also, wherein the gudgeons'will be prevented from becoming loosened by the heat of the bearings.

The inventionconsists in the novel construction and combination of the several parts, as will be hereinafter fully set forth,

the reel.

and pointed out in the claim.

Reference is to be had to the accompanying drawings, running a part of this specification, in which similar figures bf. reference indicate corresponding parts in all the views.

Figure 1 is-a plan viev. of a reel attached to the main sills of the drill-frame. Fig. 2 is an end View of the reel and the band-wheel. Fig. 3 is a central vertical section through Fig. 4 is a transverse section on line as w of Fig. 3, and Fig. 5 is a perspective view of a segment of the frictionpulley.

The prime object of the invention is to provide a sand-reel of simple and durebri;v construction purposed for'use ing connection with the sand-pump of a drill adapted forv drillwells.

In Figs. 1 and I have illustrated a por-' tion of a drill-frame and the location of the sand-reel upon such frame. The sand-reel is shown as mounted in bearings 10, attached to the main sills 1l,and the friction-pulley of the reel is shown asengaging with the bandwheel 12, also mounted upon the sills. The band-wheel carries a bull-rope 13, adapted to pass over a bullwheel. (Not illustrated.) A walking-beam 14 is shown connected with the band-wheel by a pitinan 15, and a portion of the sand-reel draw-bar i6 is also illustrated having pivoted thereto the sand-recl lever 1.7. The sand-pumpline18 is illustrated as coiled upon the reel.

InIc-arrying out the invention, the sandneel consists of a tnbularhody 19, (best shown in Fig. 3,) having a disk 20 riveted or otherwise secured at each end, trom the center of which disks a gu'dgcon 21 is outwardly projectcd,.

provided with a collar 22, to take the end friction and keep the thin end of the hollow shaft or body from cutting the bearings.

The outer extremity of the gndgeon may be made tapering, as illustrated, oncylindrical, if so desired. Upon the shaft or body 19, at one side of the center, a tubular sleeve-like casting 23 is riveted or otherwise secured, which sleevedilre casting is provided between the ends with approaching independent integral annular flanges and 25, and two or more feathers 2G are produced upon the enter face of the sleeve-like casting; 23, extending i ngitudinaliy of the same fromthe flange 25 outward to the end of said casting, as best shown in Figs. 3 and l. The friction-pulley 27 is preferably constructed of series of wooden segments 28, arranged to break joints,

as illustrated in Fig. 5, and having the grain of the wood radially of the pulley. One side of the pulley 27 so constructed is made to bear against the annular flange 25, and a de-- tachable flange 29 is bronghtin close contact with the opposite side of the pulley, as ,best illustrated in Fig. 3. The detachable flange 29 is provided with a shorthub 30, and the hub and 'fiange are grooved to receive the feathers 26, whereby the said flange is pre vented from moving upon the sleeve-like casting-23. The inner ends of the segments above the said teathers are also grooved to receive the same. The segments-constituting the frictiongulley 27ers held in close contact-.with each other and witlrthe flanges 25 and 29 by a series of tra-zisrorsely-arranged bolts 31, as .best shown in Figs. 3 and 4. These bolts are so arranged that one bolt will pass through the center of the outer-segsegments and the center of theginner segnicnt, breaking the joints of the said outer segments, as is also illustrated in Fig. 5. To this end each segment making up the pulley is provided with a central aperture 32 and an essentially transverse aligning circular reo recess 33 in the side edges." The arrangement of the several bolts 31 is plainly shown in Fig. 4. The brake-pulley 3 1 is also mounted upon the slecve like casting 23, and is securely bolted to the outer face of the flange 24. The brake-pulley 3-; may be of any approved construction, and is made to operate in the ordinary manner.

It will be observed by-reason of the construction above described of the friction-pulley that the filling or face of the pulley can never be torn away so as to destroy it, as is often the case with the old style of frictionpulley.

In order that the sand-pump line, when coiled upon the body of the shaft19, as illustrated in Fig. 1, may not slide over uponthe gudgeon 21, the said line is confined to agiven space by means of arms 35, projected radially from spaced collars 36, which collars are rigidly secured to the shaft or body, as best shown in Figs. 1 and 3.

While I have illustrated a tubular shaft and the gndgeons 21 as applied to the sand-' reel, I desire it to be distinctly understood that the same shaft is equally applicable to the bull-wheels of a well-drilling machine.

If in practice it is found desirable, paper may be substituted for the wooden segments forming the friction-pulley, or the wood or paper used in building up said pulley may consist of a series of disks or rings bolted togethensubstantially in the manner specified.

Having thus described myinvcntion. what I claim as new, and desire to secure by Letters Patent, is

The hcreii'lbefore-described improvement in sand-reel pulleys, consisting of a sleevelike casting adapted to be secured upon the shaft 19, provided with two spaced integral annular flanges upon the periphery, feathers extending from one flange to the end of the casting, a friction-pulley consisting of a series of wooden segments arranged to" break joint-s, located upon the sleeve-like casting at the feathered portions and bearing against one of the said flanges, a detachable flange engaging one face of the pulley, bolts passing through the two flanges and ,through the said pulley at the center and joints of the several segments, and a brake-pulley rigidly secured to the remaining flange, all arranged substantiallyas and for the purpose described.
